Which expression is equivalent to 2^6 x (2^2)^3? O A 212 B. 215 O c. 236 OD 254

Semenov [28]

A. $\bold{\boxed{\green{2^{12}}}}$

Answer:

Solution given:

$2^6 x (2^2)^3$

we know that

product of power and power is added and power to power is multiplied for same base only.

I.E.

product of same base but different power: $a^b+a^c=a^(b+c)$

power to power : $(a^b)^c=a^(b*c)$

By using above property

$2^6+2^{2*3}$

$2^6+2^6$

$2^{[6+6]}=2^{12}$

. You deposit $10,000 in an account that pays 6.92% annual interest. Find the balance after 5 years if the interest is compounde

leva [86]

Answer:

$13,973.16

Step-by-step explanation:

The percent is 6.92%. Make that a decimal, and it's 0.0692. To make it go up instead of down, change it to 1.0692. Now if you multiply a number with 1.0692, the number will grow by 6.92%.

10,000 x 1.0692 = 10,692 (1st year)

10,692 x 1.0692 = 11,431.8864 (2nd year)

11,431.8864 x 1.0692 = 12,222.97293888 (3rd year)

12,222.97293888 x 1.0692 = 13.068.802666250496 (4th year)

13.068.802666250496 x 1.0692 = 13,973.1638107550303232 (5th year)

13,973.1638107550303232 = $13.963.16 (5th year total in $)

Explain why the absolute value of a number will never be negative

aleksandr82 [10.1K]

The absolute value of a number will never be negative because absolute value is the distance from zero, so it will always be positive. For example, you can't be -6 away from 0, you are 6 away from 0.
