2*-27+9+√5

-45+√5

-42.76

Answer 2

Answer: If it is the sign of multiplication between 2 and 3 then the answer will be ....

17.24

Step-by-step explanation:

2×3 - 3x + √5 Here put x = -3

so , 2×3 - 3(-3) + √5

6 - (3×-3) + √5

6 -(-9) + √5

6+9 + √5 put √5 = 2.236 = 2.24 ( by doing round of )

15 + 2.24

17.24

And if it is x between 2 and 3 then the answer will be .....

2x3 -3x + √5 Here put x=-3

so , 2×-3×3 -(3×-3) + √5

we will solve it according to DMAS

-18 - (-9) + √5

-18 + 9 + √5

-9 + √5 Put √5 = 2.236 = 2.24 (do round of)

-9 + 2.24

-6.76
