Question

Which expressions are equivalent ( 0.2) 3 x ( 0.3 ) 4?

Answer 1

Hey there!

Assuming you meant….

(0.2)^3 * (0.3)^4

= 0.2^3 * 0.3^4

= 0.2 * 0.2 * 0.2 * 0.3 * 0.3 * 0.3 * 0.3

= 0.04 * 0.2 * 0.09 * 0.09

= 0.008 * 0.0081

= 0.0000648

≈ 0.000065

Therefore, your answer should be:

0.0000648

Good luck on your assignment & enjoy your day!

Answer 2

Step-by-step explanation:

$\tt{}(0.2 {)}^{3} \times (0.3 {)}^{4}$

$\tt{}0.3 \times 0.06 ^{3}$

$\tt{} \frac{3}{10} \times ( \frac{3}{50} {)}^{3}$

$\tt{} \frac{3}{10} \times \frac{ {3}^{3} }{ {50}^{3} }$

$\tt{} \frac{ {3}^{4} }{10 \times 50 ^3 }$

$\tt{} \frac{81}{10 \times 5 {0}^{3} }$

$\tt{}6.48$
