Help please! this is algebra. It says it needs to be in a fractional exponent form ONLY!​
Mars2501 [29]

Answer:

6x^{\frac{5}{6} }

Step-by-step explanation:

Using the rule of exponents

a^{m} × a^{n} ⇔ a^{(m+n)}

Given

3x^{\frac{1}{3} } × 2x^{\frac{1}{2} }

= (3 × 2) × x^{\frac{1}{3}+\frac{1}{2}  }

[ Calculate the fraction sum

\frac{1}{3} + \frac{1}{2}

= \frac{2}{6} + \frac{3}{6} = \frac{5}{6} ]

= 6x^{\frac{5}{6} }

Ahmad’s father is 4 times as old as Ahmad. After 5 years, father will be three times as old as Ahmad. Find their present ages
Ilia_Sergeevich [38]

The present age of Ahmed and Ahmed's father is 12 and 36 respectively.

Step-by-step explanation:

Given : Ahmed's father is thrice as old as Ahmed. After 12 years, his age will be twice that of his son.

To Find : Their present age ?

Solution :

Let the Ahmed's age be 'x'.

Ahmed's father is thrice as old as Ahmed.

i.e. Ahmed's father age is '3x'

After 12 years, his age will be twice that of his son.

i.e. 3x+12 = 2(x+12)3x+12=2(x+12)

Solving the equation,

3x+12 = 2x+243x+12=2x+24

x=12x=12

So, Ahmed's age is 12.

Ahmed's father age is 3\times 12=363×12=36

Therefore, The present age of Ahmed and Ahmed's father is 12 and 36 respectively.
