Age If you add Natalie's age and Fred's age, the result is 40. If you add Fred's age to 4 times

jolli1 [7]

Answer:

Fred is 28 yrs old. Nathalie is 12yrs old

Step-by-step explanation:

Let Nathalie's age be x

Let Fred's age be a

x+a=40 yrs•••••1

4x+a=76yrs•••••2

a=40-x

Substitute a for 40-x in equation (2)

4x+40-x=76

3x=76-40

3x=36

x=12

a=40-12

a=28

Express the following in exponential notation: (-4) x ... x (-4) 11 times

Anni [7]

Given:

The expression is:

$(-4)\times ...\times (-4) (11\text{ times})$

To find:

The exponential notation for the given expression.

Solution:

We know that

$a\times a\times ...\times a(n\text{ times})=a^n$ ...(i)

We have,

$(-4)\times ...\times (-4) (11\text{ times})$

Using (i), the given expression can be written as:

$(-4)\times ...\times (-4) (11\text{ times})=(-4)^{11}$

Therefore, the exponential notation of the given expression is $(-4)^{11}$ .
