Answer:
Step-by-step explanation:
When dividing, exponential powers are subtracted. When multiplying, power are added the base remains the same if the two bases are the same number. If they are different, the bases are multiplied and the same power is simply kept. With this in mind, let us solve this question!
6^3 × 2^6 / 2^3 ----- Multiplication or division can be done first. I do division because it's easier that way. 6-3 = 3
6^3 * 2^3 ------ Multiply bases and keep the power.
B.) 12^3
Hope this helps!
We don't know the number she started with, so let's call it x.
<span>Petra started with a number added 3: x + 3
</span>
<span>multiplied the result by 4: 4(x + 3)
</span><span>subtracted 6: 4(x + 3) - 6
</span>
<span>and multiplied that result by 3: 3[4(x + 3) - 6]
</span>
her final answer was 90: <span>3[4(x + 3) - 6] = 90
Now we solve the equation for x.
</span><span>3[4(x + 3) - 6] = 90
</span>
<span>4(x + 3) - 6 = 30
4(x + 3) = 36
x + 3 = 9
x = 6
The number is 6.
