Write the expression 44(4–7)(4) using a single exponent.

Ghella [55]

<h3>The given expression as single exponent is:</h3>

$4^4 \times 4^{-7} \times 4 = 4^{-2}$

<em><u>Solution:</u></em>

<em><u>Given expression is:</u></em>

$4^4 \times 4^{-7} \times 4$

In exponents,

When the base is same, exponents can be added

Which means,

$a^m \times a^n = a^{m+n}$

Therefore,

$4^4 \times 4^{-7} \times 4 = 4^{4-7+1}\\\\Simplify\\\\4^4 \times 4^{-7} \times 4 = 4^{-3+1} \\\\4^4 \times 4^{-7} \times 4 = 4^{-2}$

Thus the given expression as single exponent is:

$4^4 \times 4^{-7} \times 4 = 4^{-2}$

Select all statements that show correct reasoning for finding 15 ÷ 2/9 * Multiply 15 by 2, then divide by 9. Multiply 15 by 9, t

Jet001 [13]

Answer:

Multiply 15 by 9, then divide by 2.

Step-by-step explanation:

We need to solve the given expression.

$15\div \dfrac{2}{9}$

We know that, $a\div \dfrac{b}{c}=a\times \dfrac{c}{b}$

We have,

a = 15, b = 2 and c = 9

So,

$15\div \dfrac{2}{9}=15\times \dfrac{9}{2}\\\\=\dfrac{15\times 9}{2}\\\\=\dfrac{135}{2}\\\\=67.5$

So, the steps are "Multiply 15 by 9, then divide by 2".

What is 58,000,000,000 estimated as the product of a single digit and a power of 10?

Marina CMI [18]

Since we are estimating, round to 60,000,000,000. Now count how many decimal places you would have to move to the left to get to a single digit (until we get to 6.0). That will be your exponent...
