Question

use the law of exponent and simplify 4 raise to minus 3 into a raise to minus 5 into b raised to minus 4 / 4 raise to minus 5 into a raise to minus 8 into b raised to minus 3​

Answer 1

Answer:

= (a)^5-8 x 1/(4)^3 x (b)^-3 x (b)^ -4/4 *-5

= a^-3 x 1/64 x (b)^-3 x (b)^5

= a^-3 x 1/64 x (b)^-2
