Without multiplying, determine the sign of the product (356,864)(−194,758). the sign of the product is positive because a positive multiplied by a negative is a positive. the sign of the product is negative because a positive multiplied by a negative is a negative. the sign of the product is negative because the second number is negative. the sign of the product is positive because the first number is positive.

The correct option is 2.

Step-by-step explanation:

The given expression is

(356,864)(−194,758)

We need to find the sign of the product (356,864)(−194,758) without multiplying.

Sign of two numbers               Sign of product

 ( + ) ( + )                                        ( + )

 ( - ) ( + )                                         ( - )

 ( + ) ( - )                                         ( - )

 ( - ) ( - )                                         ( + )

13

step-by-step explanation:

169-1=168

168-3=165

165-5=160

160-7=153

153-9=144

144-11=133

133-13=120

120-15=105

105-17=88

88-19=69

69-21=48

48-23=25

25-25=0

since it took 13times to completely subtract it hence its square root is 13
