6 batteries would be 7.5 dollars because I found the cost per unit by dividing the unit amount by cost. I then multiplied the cost per unit by 6 and got 7.5, with the cost per unit being 1.25.

What expression is equivalent to 5 to the 6th power?PlZZZ HElP

Akimi4 [234]

Answer:

$5^6 = 125 * 125$

Step-by-step explanation:

The given expression can be represented as:.5⁶

Required

Find equivalent expression

$5^6$

Express 6 as 3 + 3

$5^6 = 5^{3+3}$

Apply the following law of indices

$a^{m+n} = a^m * a^n$

So, we have:

$5^6 = 5^{3} * 5^{3}$

Express $5^3$ as 125

$5^6 = 125 * 125$

Hence, option (b) is equivalent

I have a series of questions

alexgriva [62]

9514 1404 393

Answer:

0.4, 0.004, 0.004

Step-by-step explanation:

The "what" in each case is found by dividing the target value by 10. That is accomplished by moving the decimal point one place to the left.

4/10 = 0.4 ⇒ 10 times 0.4 = 4

0.04 and .04 are exactly the same value, so the last two on your list are the same:

0.04/10 = 0.004 ⇒ 10 times .004 = 0.04
