The value of the product expression is –6p^3 + 8p^2 – 10p
<h3>How to simplify the product?</h3>
The product expression is given as:
2p(–3p2 + 4p – 5)
Rewrite properly as:
2p(–3p^2 + 4p – 5)
Remove the bracket
2p * –3p^2 + 2p * 4p – 2p * 5
Evaluate the products
–6p^3 + 8p^2 – 10p
Hence, the value of the product expression is –6p^3 + 8p^2 – 10p

The sphere with the volume 1436.03 m³ has 7m long radius.
To find out the approximate length of its radius by using the formula to calculate volume of sphere is:
V= 4πr³/3
The value of π is 22/7 or 3.14.
So, V = 4 × 3.14 × r³ / 3
Volume of the sphere is given which is 1436.03 m³.
Thus, r³ = 1436.03×3 / 4×3.14
r = ³√ 4308.09/12.56 = ³√343 = 7 m.
Hence, the radius of the given sphere is 7 m.
The cube root of a number is the factor that we multiply by itself three times to get that number.
For example, the cube root of 27 is 3.
