Find m so that

According to Law of indices,

a^x × a^y = a ^{(x + y)}

Here in the question,

a = 2/9

x = 3

y = 6

∴ x + y = 3 + 6

= 9

2m – 1 = 9

2m = 10

m = 5

Arrange in descending order:

2^{2 + 3}, (2²)³, 2 × 2², 3² × 3⁰, 2³ × 5²

By what number should (– 4)⁵ be divided so that the quotient may be equal to (– 4)³?

If find the value of
