Juli2301 [7.4K]

Answer:

I pretty sure it's 8cm.

Step-by-step explanation:

I multiplied 73,000 by 0.000074, which resulted in 5.402.
Then, I multiplied 73,000 by 0.000032, which resulted in 2.336.
I added the products together, which gave a sum of 7.738.
Then I rounded to the nearest whole number, which is 8, because the tenth in the decimal (.7) rounds up because it is >4.

Plzzz help! what expersion is equivalent to it?
sladkih [1.3K]

Answer:

64x^{12}

Step-by-step explanation:

We have to use the law of indices for finding the equivalent expression.

(8x^{5})^{2} = 64x^{10}  We square 8, which is 64 and multiply the two powers.

(x^{4})^{\frac{1}{2}} = x^{2}  We multiply the 2 powers giving us, \frac{4}{2}, which simplifies to 2.

64x^{10} × x^{2} = 64x^{12}  This is the answer as we multiply the two indices together.

I hope this helps!! ^-^
