81^5=3^x What does “x” equal?

Lynna [10]

Answer:

$x =2 0$

Step-by-step explanation:

${81}^{5} = {3}^{x}$

We know that 3^4 = 81. So :

$= > { ({3}^{4}) }^{5} = {3}^{x}$

$= > {3}^{4 \times 5} = {3}^{x}$

$= > {3}^{20} = {3}^{x}$

Here both the Right hand side & Left hand side has same base i.e. have 3 as base in both the sides.

So , eliminating the base gives :-

$x = 20$

If the velocity of a bicycle is 10 m/s how long will it take to cover a distance of 18 km

Sergeeva-Olga [200]

Answer:

time taken=1800 seconds

Step-by-step explanation:

velocity=v=10m/s

distance=S=18km=18×10³m=18000m

t=?

as we know that

velocity= $\frac{distance covered}{time taken}$

velocity×time taken=distance covered

now here we have to find time

time taken= $\frac{distance covered}{velocity}$

time taken= $\frac{18000m}{10m/s}$

time taken=1800seconds
