Answer 1

$25 \times {5}^{ - 3} = {5}^{2} \times {5}^{ - 3} = \\ {5}^{2 - 3} = {5}^{ - 1} = \frac{1}{5}$

$( \frac{1}{4} )^{2} \div {( \frac{1}{4} )}^{4} = ( \frac{1}{4} ) ^{2 - 4} = {( \frac{1}{4} )}^{ - 2} = {4}^{2} = 16$

$( - 0.1 ^{ - 1} ) ^{2} = ( { - 0.1})^{ - 2} = \frac{1}{ ( - \frac{1}{10}) ^{2} } = {10}^{2} = 100$

Answer 2

а) 25 * 5⁻³ = 5² * 5⁻³ = 5⁻¹ = 1/5 = 0,2

б) (1/4)² : (1/4)⁵ = (1/4)⁻³ = 4³ = 64

в) (-0,1⁻¹)² = (-10)² = 100
