How would you solve this index laws equation

For b), the answer is 3^2 / 2^7
you just have to multiply the exponent of 2 with 2 and add it with 3

for c), the answer is -(3)^3
notice that the negative sign is outside the parenthesis

for d), the answer is 1
you just multiply -n with 3 and all the exponents since they all have the same base

for e), the answer is 2a^2 b
just distribute the exponent 2 to all the bases and cancel out the things that can be cancelled or just subtract exponents of the same bases if the operation is division

for f), the answer is b^4 / 2b^4
focus first on the things inside the parenthesis, then take not of the -1 exponent after

Answer: the correct answer is 10step-by-step explanation: let the number be n, then the expression becomes,then“twelve more than the quotient of a number and two, decreased by four” iswhen n=4,we substitute 4 whetever we see n to get,we simplify to obtain,we further simplify to get,therefore the correct answer is c.
