Question

Simplify the expression below.

Answer 1

Answer:

D. 10^10

Step-by-step explanation:

Multiplying numbers with exponents rule : $a^b*a^c=a^b^+^c$

explanation of rule : we simply keep the bases the same and add the exponents.

10^3 • 10^7

keep the base as 10 and add the exponents

$10^3 * 10^7 =10^3^+^7=10^1^0$

Keep in mind that this only works when the bases are the same.

Answer 2

Answer:

$\large\boxed{\boxed{\underline{\underline{\maltese{\pink{\pmb{\sf{\: ANSWER : \: \: \: \: 10^{10} }}}}}}}}$

Step-by-step explanation:

The given expression, 10³ • 10⁷ has the same base but different exponential values. We know that,

• $\large\sf \: a^{x} * a^{y} = a^{x + y}$

So,

$\large{\mathfrak{10^{3} * 10^{7} }}$

= $\large{\mathfrak{10^{3 + 7} }}$

= $\huge{\boxed{\mathfrak{10^{10} }}}$  (3rd option)
