Answer:
Given,
A=90
b=15
A=12bh
Now,
Step-by-step explanation:
Put the given value in the formula

Is it 5^6 - 5^11 = 5x × (1-5y)?
5^6 - 5^11 = 5^(6-11) = 5^(-5) = 1/(5^5)
So 1/3125 = 5x - 5(5y)
1/3125 = 5(x-5y)
1/3125/5 = x-5y
0.000064 = x - 5y
0.000045 = <span>00.00045 /10
=</span><span> 000.0045 / 100
</span>= 0000.045 / 1 000
= 00000.45 / 10 000
<span>= 000004.5 / 100 000 = 4.5 * 10^(-5)
That is in</span><span> scientific notation
I hope that helps
