Math help pretty please...xoxox?

Question

these equations need to be put into radicals
1.) small 4 square root of ab multiplied by small 4 square root of a^6b^3
2.) (5 small 3 square root of 3x^3)(2 small 3 square root of 18x^3)
3.) 5x(small 3 square root of 8y^6) divided by 12(small 3 square root of 64x^3)
4.) (2 small 3 square root of 4x)^3
5.) small x square root of z^x-3 multiplied by small x square root of z^3
6.) square root of t+4 multiplied by square root of t-4
thank you whovever answers all gets best answer

Answer 1

1.) small 4 Square Root (SR) with (a^7b^4) in it. which simplifies to ab (outside the SR) next to a small 4 SR with a^3 inside.
2.)30x^2 small 3 SR 2
3.)(10/3)(y^2x^2) if that little x in the problem was a times then change x^2 to x.
4.)8(4x)=32x.
5.)small x SR Z^3x - 3Z^3
6.)SR t^2 - 4
