Answer: 6400<em>x²</em> · (<em>x - 1)²</em>
The rule says: To multiply exponential expressions which have the same base, add up their exponents.
In our case, the common base is (x-1) and the exponents are:
1, as (x-1) is the same number as (x-1)1
And 1, as (x-1) is the same number as (x-1)1
The product is therefore, (x-1) (1 + 1) = (x-1)²
A boy stands 1 meter away from a lamppost. He is 1.8 meters tall and casts a shadow 2 meters long in the light from the lamp
The diagram is attached below using the given information
We have two similar triangle
Triangle ACD is similar to triangle ABE. So the sides are in proportional

AC = AB + BC = 3m

2x = 1.8 * 3 (cross multiply)
2x = 5.4
Divide by 2 on both sides
x = 2.7
Height of Lamppost is 2.7 meter
Flutes-10, 5, 2
