The square root of a number consisting of two digits isequal
Gala2k [10]

Answer:

81

Step-by-step explanation:

Let the digits that make up the number be a and b.

Given that the square root of the number is equal to the sum of the digits.

Then,

√(10a + b) = a + b

Also given that the square root of the number is less than the number obtained by  interchanging the digits by 9, then

√(10a +b) + 9  = 10b + a

Since √(10a + b) = a + b, then

a + b + 9 = 10b + a

a - a + 9 = 10b - b

9b = 9

b = 1

since √(10a + b) = a + b

√(10a + 1) = a + 1

10a + 1= (a + 1)²

10a + 1 = a² + 2a + 1

a²  + 2a - 10a + 1 - 1 = 0

a² - 8a = 0

a(a - 8) = 0

a = 0 or a = 8

Using a = 8 and b = 1,

the number 10a + b = 10(8) + 1 = 81.

How do I Evaluate [(30 + 6) − 32] ÷ 9 ⋅ 2?
djverab [1.8K]

Use PEMDAS:

P Parentheses first

E Exponents (ie Powers and Square Roots, etc.)

MD Multiplication and Division (left-to-right)

AS Addition and Subtraction (left-to-right)

[(30 + 6) - 32] : 9 · 2 = (36 - 32) : 9 · 2 = 4 : 9 · 2 = 4/9 · 2 = 8/9
