Question

"Find the cube of 2.5 and -7"

Answer 1

Step-by-step explanation:

"

$(2.5)^{3} = \frac{25}{10}^{3} = \frac{5}{2}^{3}$

= 5×5×5/2×2×2 = 125/8

• (-7)³ = (-7)×(-7)×(-7) = -343"

Answer 2

Answer:

Cube of 2.5=

${(2.5})^{3} = 2.5 \times 2.5 \times 2.5 \\ \\ = 6.25 \times 2.5 \\ \\ = 15.625$

$\rule{200pt}{5pt}$

Cube of -7

$= {( - 7)}^{3} = ( - 7) \times ( - 7) \times ( - 7) \\ \\ = - 343$
