Question

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

Answer 1

Explanation:

`\tt{}(0.2 {)}^(3) * (0.3 {)}^(4)`

`\tt{}0.3 * 0.06 ^(3)`

`\tt{} (3)/(10) * ( (3)/(50) {)}^(3)`

`\tt{} (3)/(10) * \frac{ {3}^(3) }{ {50}^(3) }`

`\tt{} \frac{ {3}^(4) }{10 * 50 ^3 }`

`\tt{} \frac{81}{10 * 5 {0}^(3) }`

`\tt{}6.48`

Answer 2

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!
