(1+5^2)-16(1/2)^3 step by step of solving this

Power: 5 ^ 2 = 25

Add: 1 + 25 = 26

Power: 1

2

^ 3 = 13

23

= 1

8

Multiple: 16 * 1

8

= 16 · 1

1 · 8

= 16

8

= 2 · 8

1 · 8

= 2

Multiply both numerators and denominators. Result fraction keep to lowest possible denominator GCD(16, 8) = 8

Subtract: 26 - 2 = 24

i found two solutions,   n = 2 • ± √3 = ± 3.4641

step-by-step explanation:

54 kilometers per hour

step-by-step explanation:

according to rules:

1 km = 1000 meter

which means that 1 meter = 1/1000 km

1 hour = 3600 second [ as 1 hour = 60 min = 60 *60 seconds ]

which means that 1 second = 1/3600 hour

therefore, 1 kilometer/hour =

thus to convert 15 meter per second to kilometer per hour, we multiply 15 to 3.6 kilometer/hour.

15 meter/second=   which is the required answer.
