Write using exponential notation? 5.5.2.2.2.2

inna [77]

Answer:

$5 ^{2} \times 2^{4}$

Step-by-step explanation:

Multiplying 5 by itself is the same thing as raising it to the second power:

$5 \times 5 = {5}^{2} = 25$

We multiply 2 by itself two seperate times. That's the same thing as raising 2 to the second power to the second power or in simpler terms raising two to the fourth power:

$2 \times 2 \times 2 \times 2 = {({2}^{2})}^{2} = {2}^{4} = 16$

Since only multiplication is present, we can combine the two terms to get:

$5^{2} \times {2}^{4}$

ASAP HELP FOR NUMBER 12, Thank you so much!!! :)

qaws [65]

12a)
5x + 45 + 3x - 25 = 180
8x + 20 = 180
8x = 160
x = 20

12b)
2x - 5 = 2(20) - 5 = 40 - 5 = 35
3x - 25 = 3(20) - 25 = 60 - 25 = 35

y = 180 - (35+35)
y = 180 - 70
y = 110

Multiply 6/5 by the reciprocal of (-3/8)

weeeeeb [17]

Answer:

-48/15, simplified to -16/5

Step-by-step explanation:

The reciprocal of -3/8 is -8/3. So the equation will be 6/5 x -8/3. Multiply numerators then multiply denominators to get -48/15. This can simplify to -16/5 by dividing both by 3.
