Question

The mass of a baseball glove is 5•5•5•5 grams. Write the mass using exponents. Then find the value of the expression

Answer 1

x * x = x^2
Using the preceding rule 5*5*5*5=5^4=625 grams is the mass of the baseball glove.

Answer 2

Mass of Baseball glove =5×5×5×5

⇒Value of mass in terms of exponents(Using the Property)

`x^a * x^a * x^a......\text{n times} =x^(na)\\\\\rightarrow 5^1 * 5^(1)* 5^(1)* 5^(1)\\\\=5^(1+1+1+1)\\\\=5^4---\text{Exponent}\\\\=625\text{gram}--\text{Value of the expression}`
