Please help

madam [21]

Answer:

Step-by-step explanation:

1 × a = a

a² = a*a ; a³ = a*a*a .....

$(\frac{a}{b}) ^{n} = \frac{a^{n} }{b^{n} }$

(1).

(a). $7^{5}$

(b). $(\frac{1}{7}) ^{6}$ = $\frac{1}{7^{6} }$

(c). $(9.3)^{9}$

(2).

(e). $(\frac{1}{2} )^{4} =\frac{1}{2^{4} }$ = $\frac{1}{2*2*2*2}$ = $\frac{1}{16}$

(f). $(\frac{1}{3} )^{2}$ = $\frac{1}{3}$ × $\frac{1}{3}$ = $\frac{1}{9}$

(3).

x² = 30² + 16² = 900 + 256 = 1156 = 34² ⇒ x = 34 units

Simplify 3[2^3 + (4-2)^3 - (6-2)^2]

Ivahew [28]

Answer:

$\boxed{0}$

Step-by-step explanation:

$3(2^3 + (4 - 2)^3 - (6 - 2)^2)$

$= 3(2^3 + 2^3 - 4^2)$

$= 3(2.2^3 - (2^2)^2)$

$= 3(2^4 - 2^4)$

$= 3(0)$

$= 0$

A leprechaun places a magic penny under a girl's pillow. The next night there are 2 magic pennies under her pillow. The followi

marta [7]

Answer:

Step-by-step explanation:

Since the pennies need to be kept under the pillow in order to be doubled, we're really looking for the day the girl will wake up with 5 billion pennies under her pillow.

The general formula of that geometric sequence will be: t = 1 + 2^(n-1)

We need to find the value of n when t will be over 5,000,000,000.

So, the equation becomes:

5,000,000,001 = 1 + 2^(n-1)

2^(n-1) = 5,000,000,000

log(2^(n-1)) = log(5,000,000,000)

(n-1) * log(2) = log(5,000,000,000)

n-1 = log(5,000,000,000) / log(2)

n-1 = 22.25

n = 33.25

Since it has to be complete days, and we have to reach over 5 billion, then we round it up to 34.
