If you raise 4 to the 214th power what is the units digit

4²¹⁴.
Note that if the exponent is ODD , the unit digit is always 4:
4¹ = 4,  4³ = 64,  4⁵ = 1024 ... 4¹⁵ = 1,073,741,824, etc.
But when the exponent is EVEN, the last digit is always 6:
4² = 16,  4⁶ = 4,096,  4⁸ = 65,536, ...4¹⁶ = 4,294,967,296

By induction we can say that the last digit of 4²¹⁴ is 6, because the exponent is EVEN

Ifound this on google “that means that the graph of a function with direct variation has these features: it is a straight line: because the slope is the ratio y/x = k. it passes through the origin (0,0): because y = kx = k (0) = 0.” i hope this you for what your looking for
