Question

Evaluate the expression 14.3 minus 2 times 5 to the 2nd power divided by 5

Answer 1

Answer:

4.3

Step-by-step explanation:

We are given that an expression

$14.3-2\times 5^2\div 5$

We have to find the value of given expression.

DMAS rule:

D=Divided first

M=Multiply

A=Addition

S=Subtraction

Using DMAS rule ,

We  solve  first divide operation

$14.3-2\times 5^{2-1}$

Using property: $a^x\div a^y=a^{x-y}$

Then, we get

$14.3-2\times 5$

Now, we solve multiply operation

$14.3-10$

Now, we solve subtraction operation

$4.3$

Hence, $14.3-2\times 5^2\div 5=4.3$

Answer 2

The answer is :61.5
14.3-2=12.3
12.3(5^5)=307.5
307.5÷5=61.5
