I need help in math?

Question

1- Use the properties of exponents to rewrite the expression. (0.35) (0.35) (0.35) (0.35) (0.35)

2- Write the expression in expanded form. Then write the product in exponential form. 3(2) * 3(4)

Write the expression using single exponent.

3- 4(5) * 4(4)

4- Write 676,000 in scientific notation.

5- Write 54,200,000 in scientific notation.

6- Write the number in standard notation. 8 X 10 (9)

Answer 1

Yes, you do.

1. .35^5
2. Expression makes no sense. Use standard symbology.
3. Ditto
4. 6.67 e5
5 5.42 e7
6.8000000000

Answer 2

Answer 1:
(0. 35)^5

Answer 2:
I think you mean:
3^2 * 3^4
= 3^(2 + 4)
= 3^6
= 729

Answer 3:
I suppose you mean:
4^5 * 4^4
= 4^(5 + 4)
= 4^9

There's no way you can write 4*5*4*4 as a single base with an integer exponent. Same goes for the previous one, if the brackets meant multiplication.

Answer 4:
676 * 10^3
= 6.76 * 10^5

Answer 5:
542 * 10^5
= 5.42 * 10^7

Answer 6:
8000000000

Answer 3

1. (.35) ^ 5

I think you're notating the exponents wrong. Makes it confusing about what the actual question is. Write it like this: a^b (a is raised to the power of b)

2. (3)(3) * (3)(3)(3)(3)
3^6 = 729

3. Do it the same as above

can't help you on 4-6. Scientific notation is such crap, never understood that stuff.

Answer 4

1. (0.35) to the power 5 i.e., (0.35)^5
2. perhaps you wnat 3^2 * 3^4
3^(2+4)
3^6

3. Similarly 4^5 * 4^4
4^(5+4)
4^9

4.6.76 * 10 ^5

5. 5.42 * 10^7

6. I am not sure, perhaps the answer is 8.0 x 10^9

In all answers '*' denotes 'multiplication'
'^' denotes 'to the power'

Answer 5

4. 6.76 to the 5th power

5. 5.42 to the 7th power

6. 8000000000

Answer 6

Use MathXL, very good program.
