2^2*2^3*2^2
Let's evaluate: 22×23×22
ⓘ Multiplying powers with the same base adds the exponents: 22×23×22 = 22 + 3 + 2
22 + 3 + 2
ⓘ The exponent is computed before the power: 2 + 3 = 5
25 + 2
ⓘ The exponent is computed before the power: 5 + 2 = 7
27
ⓘ An integer power is a repeated product: 27 = 2×...×2, 7 times = 128
▶Result:   128
