1 answer:
If you choose to fully simplify this expression, then the answer is b^3
If you just want to convert to rational exponent form, then the square root will be replaced with an exponent of 1/2. The rule is sqrt(x) = x^(1/2)
So,
sqrt(b^6) = (b^6)^(1/2)
which can be written as
note how the exponents 6 and 1/2 multiply to 3, which is why the fully simplified version is b^3

Answer:
The surface area is
Step-by-step explanation:
we know that
The surface area of a square pyramid is equal to the area of the square base plus the area of its four lateral triangular faces.
so
we have
substitute the values
3 x 2.5 = 7.5
7.5 x 1.05 = 7.8750
Note : remember to always line up the decimal points.
Hope this helps
