Answer: 81/100
Step-by-step explanation:
I don't guarantee you I am right but..
first, solve for the exponents after substituting the numbers in
3/5 x 3/5 is 9/25
since b's exponent is negative, you change the fraction into its reciprocal and then do it with the exponent but positive
2/3^-3 to 3/2^3 and 3/2 x 3/2 is 9/4
then you mutiply both numbers to get 9/4 x 9/25 is 81/100
(x^2+4)^2 + 32 = 12x^2 + 48 .... a = x^2 + 4
<span>(x^2 + 4)^2 + 32 = 12(x^2 + 4) </span>
<span>a^2 + 32 = 12a </span>
<span>a^2 - 12a + 32 = 0 </span>
<span>(a - 8)(a - 4) = 0 </span>
<span>a = 8 and a = 4 </span>
<span>for a = 8 ... 8 = x^2 + 4 ... x^2 = 4 ... x = +/- 2 </span>
<span>for a = 4 ... 4 = x^2 + 4 ... x^2 = 0 ... x = 0 </span>
<span>x = -2, 0, +2 so your answer is going to be e
</span>

Answer:
7.8 × 10^-4
Step-by-step explanation:
Although this answer is perfectly O.K., most commonly the base, or the 0.00078, is written as a number with just one digit to the left of the decimal.
To format your number in this way, we'll multiply the .00078 by 10, 4 time(s), making it a 7.8.
We do this, because each multiplication by 10 moves the decimal point to the right one digit.
But in order to keep our number the same number, we must have a × 10-4 next to the 7.8.
So, the final answer is 7.8 × 10^-4
