Question

Help. please and thank you

Answer 1

Choose the correct simplification of the expression the quantity a to the 2nd power over b to the 5th power all raised to the 3rd power.

a to the 6th power over b to the 15th power
a to the 5th power over b to the 8th power
a over b to the 15th power
a^6b^15

Answer 2

The first one. Write it out as (a^2/b^5)x(a^2/b^5)x(...) thereforeyou would do the normal addition rule of the exponents if you multiplying, so you add the exp. therefore when you have a sum like this, the quickest rule is to times within the bracket eg (a/b)^3 = a^3/b^3

Answer 3
