Choose the correct simplification of the expression (2ab5)3. (1 point) Question 8 options: 1) 8ab15 2) 8a3b8 3) 5a3b15 4) 8a3b15

d1i1m1o1n [39]

Answer:

4). $8a^{3}b^{15}$

Step-by-step explanation:

The Given expression is that,

$(2ab^{5})^{3}$

On simplifying,

$(2ab^{5})^{3}$ = $(2ab^{5} )(2ab^{5}) (2ab^{5})$

= $(2^{3} ) * (ab^{5})^{3}$

= (2×2×2) × ( $ab^{5}$ × $ab^{5}$ × $ab^{5}$ )

= $8a^{3}b^{15}$

Thus, <u>option 4</u> i.e. $8a^{3}b^{15}$ is the correct simplification of the given expression.

Now consider the product of a nonzero rational number and an irrational number. Again, assume x = , where a and b are integers a

vovangra [49]

Answer:

Irrational number

Step-by-step explanation:

It's given,

y = $\frac{mb}{na}$ (By simplifying the product of rational number 'x' and an irrational number 'y')

Where m and n are the integers and $\frac{b}{a}$ is a rational number.

(Since x = $\frac{a}{b}$ is a rational number)

Therefore, $\frac{mb}{na}$ will be a rational number.

y = $\frac{mb}{na}$ ⇒ Irrational number = Rational number

which is a contradictory statement.

Therefore, multiplication of rational and irrational number will be irrational.
